Mass Medical Strains Seeds Sour Kernel

Strain Overview

Sour Kernel seeds by Mass Medical Strains are feminized, mostly sativa cannabis seeds bred for vigorous growth, fast flowering, strong branching, and high yield potential. With an 8–9 week flowering time, Sour Kernel seeds perform well indoors, outdoors, and in greenhouse environments while delivering dense flowers and an intensely sour aromatic profile.

Genetics & Lineage

Sour Kernel seeds combine Sour Diesel (Skunktek cut) with Kernel PuTang. Sour Diesel contributes classic sour fuel genetics, vigorous sativa structure, and strong branching, while Kernel PuTang adds haze influence, flowering efficiency, and additional terpene complexity. The result is a modern sour-dominant hybrid rooted in proven legacy genetics.

Growth & Flowering

Plants grown from Sour Kernel seeds are vigorous and can stretch up to 3x their vegetative height during flowering. Strong, efficient branching creates a full canopy with numerous flower sites, while dense buds stack weight quickly during the final weeks. Sour Kernel typically finishes in 8–9 weeks and offers excellent yield potential for a sativa-leaning hybrid.

Aroma & Flavor

Sour Kernel seeds produce an exceptionally pungent terpene profile dominated by sharp sour diesel, fuel, and skunk aromas. Haze-inspired citrus, herbal, spice, and earthy notes add complexity beneath the intense sour-gas character. Aroma becomes increasingly pronounced as flowers mature.

Cultivation & Seed Type

Sour Kernel seeds are exclusively feminized and suitable for indoor, outdoor, and greenhouse cultivation. Their rapid growth and strong flowering stretch allow for shorter vegetative periods, while standard topping and training techniques can help manage the vigorous structure and maximize canopy development.

Breeder Information

Sour Kernel seeds are bred by Mass Medical Strains as a modern interpretation of classic sour genetics. By crossing the Skunktek Sour Diesel cut with Kernel PuTang, Mass Medical Strains created a high-yielding, fast-flowering hybrid that emphasizes vigorous growth, dense floral development, and powerful sour-dominant terpene expression.
